  Oh woops. Sorry, did a `git diff` rather than staging stuff.

  God, I've been using Python/JS so long I forgot about hashing map keys at the lower level.
  
  Hmmm, that means I could break updateEntry into 3 functions (abstract code/ update by index / update by name).

  There's one other reference to `object->index()` in `insert(Type *object)`, but I think that was only used by StreamRestore to populate the notification stream in `Context::streamRestoreCallback`. If that's the only use, we could remove that function.

  Yeah I think so too. I meant more like hiding the icon under the "Stream Restore" tab or using a different icon for everything other than the "notification" stream.
